I had a couple of computers stolen recently. They valued them together at $3500. One was from '03 and the other from '09. If I take cash, they give me depreciated value, which amounts to $800 total. But if I replace it they'll reimburse up to $3500. So I may as well, right? I wouldn't know how to spend $3500 on a pc if I tried.
I'm not a huge gamer, but I use SolidWorks a lot so I need solid processing power in both the CPU and GPU. I'm sure a high-end gaming pc would be overkill... but given the situation, why not?
I walked into my local big-box retailers and they all tap out at $1300 to $1700.
Without spending cash on GPU's for gaming you could still spend a ton of money just getting a top of the line PC. Intel Core i7 hexacore, 24gb of ram, dual SSDs in RAID (or more), the price will shoot up REAL quick.
